用python查询B站up主的关注时间、关注了多久

from datetime import datetime
import webbrowser

uid = input('uid:')  # 这里输入up主的uid

webbrowser.open('https://api.bilibili.com/x/space/acc/relation?mid=' + uid)
# 上面那个接口需要登录，写爬虫很麻烦所以偷懒用浏览器访问了，
# 找到mtime项粘贴进来就行
mtime = int(input('mtime:'))

follow = datetime.fromtimestamp(mtime)
print('follow-time:', follow)  # 关注日期
now = datetime.now()
print('now:', now)  # 现在
print('delta-time:', now - follow)  # 间隔时间
